TURNSTILE APPARATUS.

SPECIFICATION formingpart of Letters Patent No.761,01'7, dated May 24, 1904.

Original application filed January 3, 1903, Serial No. 137,719. Divided and this application filed September 2, 1903. Serial 1 v No. 171,703. (No model.)

To all whmn/ it may concern:

Be it known that I, EDWIN H. SPEAR, acitizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Turnstile Apparatus, of which the following is a specification. 5

This invention relates to certain new and useful improvements in turnstile apparatus, and is a division of my application, Serial No.

137,719, filed January 3, 1903.

The invention aims to construct an apparatus of the class referred to adapted when operated to permit of the passage of a person I5 through the turnstile after the necessary admission has been paid or to permit of the passage of a number of persons through the turnstilgi after a number of admissions have been pai The invention further aims to construct an apparatus of this character which is adapted to lock the turnstile to prevent its operation immediately upon the passage of'a person or persons through the turnstile for which the 2 5 admission or the number of admissions has or have been paid.

With the foregoing and other objects in view the invention aims to construct a turnstile apparatus which sh all be simple in its construction, strong, durable, efficient in its use, and comparatively inexpensive to set up.

To this end the invention consists of the novel combination and arrangement of parts hereinafter more specifically described,illus 3 5 trated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is bad to the accompanying drawings,

4 forming a part of this specification, wherein like reference characters denote corresponding parts throughout the several views, and in which Figure 1 is a perspective view of the turnstile-shaft, the radial arms thereof being shown in dotted lines, and the operating means for the controlling-pawl. Fig. 2 is an elevation of the means for returning the turnstile-shaft device for the controlling-pawl.

to its normal or looking position. Fig. 3 is a sectional detail of the means for limit- 5 ing the movement of the controlling-pawl and means for returning the pawl to its normal position. Fig. 4. is a detail of the releasing Figs. 1 and 4. are sectional details of the controlling-pawl 5 5 and its supporting means. Fig. 5 is a side elevation of the turnstile apparatus. Fig. 6 is a top plan View of the turnstile apparatus, showing the entrance of a passage-way. Fig. 7 is a sectional plan of the locking and releasing mechanism for the turnstile employed for both constructions and shown in connection with the single-admission apparatus. Fig. 8 is a detail view of the throwing device for both constructions of turnstile which is adapt- 6 5 ed to impart the necessary movement to the turnstile-shaft if it be retarded in any manner, and Fig. 9 is a detail view of the lockingpawl and ratchet employed in both constructions of turnstile and which are adapted to ar rest the movement in one direction of the turn stile-shaft.

Certain features of construction employed in both forms of the turnstile apparatus are identical and will be referred to by the same reference characters-that'is to say, certain elements referred 'to by the same reference characters are employed in the turnstile apparatus for one or more admissions and in the turnstile apparatus for a single admission. The turnstile apparatus for one or more admissions is principally shown in Fig. 1, and the turnstile apparatus for asingle admission is principally shown in Figs. 5 and 6, and referring to said Figs. 1, 5, and 6, as well as 5 Figs. 7, 8, and 9,1 denotes the vertical shaft of the turnstile, which carries near its upper end the fixed sleeve 2, provided with the radially-extending arms 3. The lower end of the shaft 1 is mounted in a suitable bearing i. 9 and above its lower end carries a fixed ratchetwheel 5, adapted to be engaged by the dogs or pawls 6 (see Fig. 9) for arresting the movement in one direction of the turnstile. Above the ratchet wheel 5 upon the shaft 1 is mounted a lockingdisk 7. The latter is provided with four radially-extending locking-ears 8, having one side thereof beveled, as at 9. Fixed upon the shaft 1 a suitable distance above the locking-disk 7 is a square disk 10, engaged by a pivoted throwing-arm 11, having a pin 12, carrying a coil compressionspring 13. The function of the disk 10 and the spring-pressed throwing-arm 11 will be hereinafter referred to.

The reference character 14 denotes one wall of the entrance-way 15, or, in other words, the passage-way through which a person or persons may be permitted to pass when the turnstile is released, and one of the radial arms 3 of the turnstile is adapted to project transversely of the passage 15 to close it.

The reference character 16 denotes a support in the form of a casing and upon which a part of application Serial No. 137,719, filed January 3, 1903, of which this application is a division, and which is also adapted to have arranged therein the locking mechanism, to be hereinafter referred to, and this support also forms the other wall of the entrance-way 15. The support or casing 16 is provided with an elongated opening 17 to permit of the movement of the radial arms 3 when the turnstile is operated. The pawls 6 and the springpressed throwing-arm 11 are pivoted in any suitable manner to and within the support 16, so as to engage, respectively, the ratchetwheel 5 and disk 10. Extending through the top 17 of the support 16 is the upper end of the shaft 1. This upper end of the shaft 1 projects into a casing 18 and carries a beveled face gear 19, which is adapted to engage and operate the gear-wheel 20, carried by the sleeve 21, mounted upon the operating-shaft 22. The size of the gear 19 is such that one revolution thereof will rotate the gear 20 four times, or four revolutions of the gearwheel 20 will equal but one revolution of the gear-wheel 19. This is necessary, owing to the fact that the radial arms 3 extend substantially at ninety degrees, one hundred and eighty degrees, two hundred and seventy'degrees,and three hundred and sixty degrees, as the movement of one arm, which is ninety degrees, permits of the passage of one person. When one of the radial arms 3 extends transversely of the passage-way 15, the latter is closed. The shaft 22 is supported in any suitable manner within the casing 18.

In Figs. 1 and 7 of the drawings is shown an electrical mechanism for releasing, respectively, the .latch 144 or the latch 7 O. The latch 144 is employed in connection with the turnstile apparatus for one or more admissions, and the latch 7 O is employed in connection with the turnstile apparatus for a single admission. The latch 144 will be hereinafter referred to. The electrical mechanism for releasing the latch 144 or 7 0 consists of a contact 59 and a contact-spring 65. The latter is secured to the l'ower face of the contact 59, as at 66, and extends around and over the upper face of said contact 59. The contact 59-is connected to the positive wire 64 of an electrical circuit, and the contact-spring 65 has connected'thereto the negative wire 67 of the electrical circuit. spring 65 engages the contact 59, the electrical circuit is closed, and the function of forming the circuit will be hereinafter referred to. The wires 64 and 67 are connected to an electrical supply 68 and. communicate with an electromagnet 69.

The latch 70 is provided with a beveled face, which is adapted to engage the ears 8 on the When the contactlocking-plate 7 and prevent the rotationof the shaft 1 of the turnstile. The latch 7 0 is spring-pressed by means of the coiled spring 71, arranged in the casing 72. The latch .70

is also arranged in the casing 72 and bears at one end against the spring 71 and is cutaway at its inner portion to form a shoulder 73,

adapted to be engaged by a holding-arm 74, carried by an armature 75, which ispivoted, as at 76, and connected to a return-spring7 7 When the circuit is closed, the magnet 69 is energized, drawing the armature 75 thereto, carrying the holdingarm 74 therewith and from engagement with the latch 7 0, thereby releasing the latch 70, so that the same can be moved inwardly in the casing 72 against the tension of the spring 71, and permitting the turnstile to rotate, as the ears 8 will then pass the latch 70. When the circuit is broken, the armature 75 is released, and through the action of the spring 77 the holdingarm 74 will be brought in engagement with the shoulder 73 and arrest the inward movement of the latch 70, thereby preventing'the turnstile from turning, as-the ears 8 on the disk7 cannot then pass the latch 70.

\ The disk 10, carried by the shaft 1, is square,

shown in Fig. 6 and impart the necessary movement to the turnstile.

The latch 144, employed in the turnstile apparatus for one or more admissions, is provided with a shoulder 145, which is engaged and held in its locking position by means of the electrically-operated releasing mechanism in the manner as hereinbefore described; The latch 144 has connected thereto a rod 146, which is pivoted, as at 147, to the link 148, the latter in turn being pivoted, as at 149, to a bar 150, fixed at one end, as at 151, to a vertically-extending rock-shaft 152. The bar 150 has connected thereto, as at 153, one end of a coiled spring 154, while the other end of the coiled spring 154 is fixed within the support or casing 16. The spring 154 is adapted to rock the shaft152 when the shaft 1 is released. The upper end of the shaft 152 carries an arm 155, which is fixed to the shaft 152, as at 156, and on its free end carries a pin 157, which is connected to a guide-bar 158,0peratingin asuitable guideway 159. (Indicatedin dotted lines, Fig. 1.) The guidebar 158 has pivotally connected thereto, as at 161, one end of a pawl 162. One side of the pawl 162 is beveled, as at 163, and the other side is provided with a lug 164. The pawl 162 is termed a controlling means for controlling the movement of the turnstile, and the operation of the pawl 162 and its connections, as hereinbefore described, will be hereinafter referred to. The vertical shaft 1 in thisconstruction extends within a casing 165, Fig. 2, and carries a beveled-face gear,which is adapted to engage and operate the gear-wheel 20, carried by the sleeve 21, mounted upon the shaft 22, these parts being of the same construction as hereinbefore referred to, the same reference characters being applied thereto. The

' shaft 22 is supported in any suitable manner within the casing 165 and carries at one end a gear-wheel 166, meshing with a gear-wheel 167 of the same diameter. The latter is mounted upon the operating worm-shaft168, suitably supported in the bearing 169.

The reference characters 17 8, 179, 180, 181, and 182 denote a series of controlling-blocks, each of which is adapted to limit the movement in one direction of the controlling-pawl 162, and the said blocks 17 8, 179, 180, 181, and 182 are operated in accordance with the number of admissions paid. Each of the control ling-blocks is also adapted for moving .the pawl 162 against the worm-shaft 168, so that as said shaft 168 revolves it will cause the pawl 162 to return to its normal position. The block 178 is used to limit the movement in one direction of the pawl 162 when a single admission is paid. The block 179 is used for the same purpose as block 178 when two admissions are paid. The block 180 is used for the same purpose as the block 17 8 when three admissionsare paid. The block 181 is used for the same purpose as block 17 8 when four admissions are paid, and the block 182 is used for the same purpose as block 178 when five admissions are paid. As before stated, the blocks 17 8 to 182, inclusive, not only limit the movement in one direction of the pawl 162, but are also adapted to move the pawl 162 against the worm-gear 168, and to obtain these two functions the blocks 17 8 to 182, inclusive, are moved in the path of the pawl 162. The controlling-blocks are moved in the path of the pawl 162 through the medium of a plurality of push-rods, ,one rod for each block, and the construction and arrangement of these push-rods are set forth in application Serial No. 137,719, filed January 3, 1903, of which this application is a division. The controlling-blocks are supported in any suitable manner and are returned to their inoperative position in any suitable manner, but preferably in the manner as set forth in application Serial No. 137,719, filed January 3, 1903, of which this application is a division.

The normal position of the pawl 162 is that as shown in Fig. 3, with its stud or lug 164 engaging the spiral of the operating wormshaft 168 at one end thereof and lying upon the guide-bar 158. The pawl 162 is retained upon the guide-bar 158 by means of a springpressed pin 210, carried by the guide-bar 158, Fig. 4 and this pin 210 is adapted to engage in one of the recesses 211 212, formed in the shaft 214. This rocking of the shaft 214 will carry therewith the depending arm 216, which has its lower end connected to the pullingbar 217. The latter is provided with a hooked end 218 and adepending pin 219. The hooked end 218 of the pulling-bar 217 is adapted to lie at one side at one end of the pawl 162', Fig. 3, so that when the shaft 214 is rocked, by means of the operation of the plate 213, the pulling-bar 217 will be carried therewith in a transverse manner and move the pawl 162 from its engagement with the spiral of the worm-shaft 168. The movement of the pawl 162 by the hooked end 218 of the pulling-bar 217 is such that when the pulling-bar is operated and moves the pawl 162 the pin 210 will ride out of the recess 211 and the hooked-end 218 of the pulling-bar will be drawn free of the end of the pawl 162. At this time the pin 210 will engage in the recess 212. The pawl 162 will then be set at an inclination upon the guide-bar 158. The pawl 162 will be retained in such position until the beveled side 163 thereof will engage with the corner of the lowered controlling-block and move the pawl 162 back on the guide-bar 158, so that the pin 210 will engage in the recess 211 and hold the pawl 162 in such position, so that its stud 164 will engage the spiral of the worm 168, and it will be obvious that as the worm 168 rotates the pawl 162 and the guidebar 158 will be returned to their normal positions, as shown in Fig. 3.

The pin 219 of the pulling-bar 217 has connected thereto a spring 220, so that the pulling-bar 21.7 after the controlling-block hasbeen elevated will be caused to return to its normal position, as shown in Fig. 3. When the pulling-bar 217 returns to its normal position, it will also return the plate 213 to its normal position, as shown in Fig. 4, for the reason that the pulling-bar 217, arm 216, shaft 214, and plate 213 are rigidly connected and movable together.

In the construction shown in Fig. 2 it may be well to state that the rotation of the worm 168 is the same as the shaft 22-that is, it revolves four times to one revolution of the facegear 19. If the pawl 162 has been set for one admission, one revolution of the worm 169 will return the pawl to its normal position, thereby preventing more than one person passing through the entrance or passage way 15. If the pawl 169 has been set for two admissions, two revolutions of the worm 169 returns the pawl to its normal position, thereby preventing more than two persons passing through the entrance or passage way 15. If the pawl 162 has been set for three admissions, three revolutions of the worm 169 will return the pawl to its normal position, thereby preventing more than three persons passing through the entrance or passage way 15. If the pawl 162 has been set for four admissions, four revolutions of the worm. 169 will return the pawl to its normal position, thereby preventing more than four persons passing through the entrance or passage way 15. If the pawl 162 has been set for five admissions, five revolutions of the worm 169 will return the pawl to its normal position, thereby preventing more than five persons passing through the entrance or passage way 15. This operation can be extended indefinitely by increasing the number of spirals forming the worm 169 and also increasing the number of controlling-blocks and push-rods correspondingly.

The operation of the worm as well as the turnstile is controlled by the controllingblocks pawl 162 as well as the shaft 152.

The operation of the turnstile which is employed in connection with one or more admissions is as follows: It will be assumed that the controlling-pawl 162 is in the position as shown in Fig. 3 and that the electrical releasing mechanism has been operated to withdraw the holding-arm 74 out of the path of the latch 144, so that the turnstile can operate. The action of the spring 154 will rock the shaft 152 and carry the guide-bar 158 along its guideway, the guide-bar 158 carrying the pawl 162 therewith. When the controlling-block 179 is lowered, it will engage the plate 213 and rock the shaft 214, thereby causing the pulling-bar 217 to move the pawl 162 out of engagement with the spiral of the worm-shaft 168. This will permit of the guide-bar 158 being moved along the guideway by the arm 155, carried by the shaft 152. The position of the pawl 162 will then be at an inclination upon the guide-bar 158 and the pin 210 will engage in the recess 212, thereby holding the pawl 162 in an inclination. The controllingblock 179 having been lowered in the manner as just described it will be in the path of the pawl 162, so that when the pawl 162 travels rearwardly owing to the operation of the shaft 152 in a manner as set forth the beveled edge 163 of the pawl will be engaged by the corner of the controlling-block, which will restore the pawl 162 to its normal position upon the guide-bar 158 and so that the pin 210 will engage in the recess 211 and hold the pawl 162. The stud or nose of the pawl 162 will then be brought against the spiral of the worm 168, and as the worm-shaft 168 is rotating it will be evident that the pawl 162 will be brought to its normal position, as shown in Fig. 3, thereby permitting of the rotation of the turnstile until the pawl 162 is brought to its normal position, as just set forth. The return movement of the pawl 162 will cause the shaft 152 to assume its normal position, and the latch 144 will have its shoulder engaged by the holding-arm 74 of the locking mechanism, or, in other words, the arm 154 will be moved in the path of the latch 145, consequently locking the turnstile. The operation of the turnstile in this particular will be such that only two persons can pass through the entranceway. After the second person has passed the pawl 162 will be in the position as shown in Fig. 27 and the holding-arm 74 will engage the latch 144 and. prevent the inclined edge of the ears on the disk 7 from riding past the latch, thereby locking the shaft 1 from movement. The operation in connection with three, four, or five admissions is the same as that in connection with two or a single admission, the controlling-blocks regulating or stopping the rearward travel of the pawl 162 and causing it to engage with the worm 168, so that as the worm rotates it will carry the pawl 162 back to its normal position, as well as restoring the shaft 152 to its normal position, so th at through the intervention of the bar 150, link 148, and rod 146 the latch 144 will be moved so it can be engaged by the locking mechanism, or, in other words, the holding-arm 74.

It is thought the many advantages of a turnstile apparatus constructed in accordance with the foregoing description, taken in connection with the accompanying drawings, to permit of the passage of a person through the turnstile after the necessary admission has been paid or to permit of the passage of a number of persons through the turnstile after a number of admissions have been paid can be readily understood, and it will, furthermore, be evident that changes, variations, and modifications can be. resorted to without departing from the spirit of the invention, and I therefore do not wish to restrict myself to the details of construction hereinbefore described and as shown in the accompanying drawings, but reserve the right to make such changes, variations, and modifications as come properly within the scope of the protection prayed.
